No. Google Apps Sync for Microsoft Outlook doesn't work with the Mac. This is because Microsoft Outlook for Mac doesn't support the Messaging Application Programming Interface (MAPI), which is required for Google Apps Sync to communicate with Outlook.

Data that isn't supported by Google Apps or is otherwise incompatible includes Outlook tasks, journal entries, notes that aren't in your top-level Notes folder, follow-up flags, distribution lists, and rich formatting in contacts. You can continue to use these features in Outlook, and in some cases you can use equivalent features in Google Apps, but the data isn't synchronized back and forth. For a complete list of functions that aren't synchronized, see the feature compatibility chart.

All your Google Apps mail, calendar events, and contacts, as well as notes in Outlook's top-level Notes folder, will be available to you over the web from any computer. For more information, take a look at this feature compatibility chart.
